Project PLAN* is a computer managed, individualized learning system developed by the Westinghouse Learning Corporation, and adopted in the St. Louis Public Schools. A summative evaluation of the system was performed. The use of a computer in Project PLAN* allows the teacher more time to spend with individual students and contributes toward record keeping and feedback on student progress. Project PLAN* was evaluated in the elementary grades using the Metropolitan Achievement Test in grades 1, 2, 3 and using the Iowa Test of Basic Skills in grades 4, 5, 6, 7. Affective measures were also used to determine the difference in the students' self-esteem, general anxiety, and test anxiety. Other activities of the evaluation included student and teacher questionnaires and a cost analysis. Mixed results were reported in the evaluation, some of which could be attributed to known contamination of the data. (WH)
